Job description

About Finfo

We help organisations consolidate disparate data feeds. We are data agnostic but generally we pull in finance, operations, ESG, and employee service consumption data into clear, engaging reporting through our Finfo 360 platform that activates curated reporting, monthly roll‑ups, role‑based summaries, and financial statements that turn noise into signal for employees, managers, leaders and their customers.

We're a small, friendly, fully remote team trusted by the NHS, L'Oréal, Yorkshire Building Society, Merlin, and McCarthy Stone (who named us Supplier of the Year).

Where are we heading? Our ambition is to evolve our current dynamic reporting into an actionable intelligence platform. Leveraging AI and building privacy enabled enterprise agents to build an ecosystem that delivers powerful tools to help our clients and their employees to understand their data.

That's where you come in. We're growing a team to take us from consolidated reporting (Today) to that trusted, actionable intelligence platform (Next). This role sits in the middle of that work : strengthening the core, shaping the frontend, and prototyping the future.

Your Mission

Your mission is to be our versatile and creative full‑stack developer, providing critical support to the team across our entire platform. You will immediately contribute to our core PHP backend, support our frontend, and bring our most creative ideas to life by 'playing' with new technologies such as AI, to discover and prototype future product lines.

This is a pivotal growth opportunity for a curious and ambitious developer to work at the heart of our platform and its innovation.

What You'll Be Doing

• Enhance Our Core Platform : Take on a key role in enhancing our core PHP backend. You'll work directly with the team to ship new features, resolve bugs, and improve application performance.
• Build & Evolve the User Experience : Contribute to our frontend using Vanilla JS and Tailwind CSS to build features and improve usability. This role has a clear growth path for you to take on more ownership and help lead our future frontend strategy.
• Be Our AI Innovation Scout (R&D) : Be our go‑to person for Research & Development. You'll get to 'play around' with new technologies (especially AI agents), build proof‑of‑concepts, and help us decide what's next.
• Learn and Grow : Embrace the opportunity to rapidly develop your skills across the entire technology stack with direct, hands‑on mentorship from the founders & leadership team.

Who You Are

• Naturally Curious & Experimental : You love to 'tinker' and explore new technologies. You have a demonstrable interest in the AI space and are excited to build prototypes from rough ideas.
• Collaborative & Eager to Learn : You're a proactive communicator who thrives on feedback, asks questions, and has a strong desire to learn from and grow with the team.
• A Pragmatic Problem‑Solver : You value building efficient, effective solutions. You're motivated by the philosophy of tools like Livewire and HTMX—getting the job done well without unnecessary complexity.
• Remote‑native, steady operator : Comfortable in a quiet, fully remote setup — able to self‑manage, communicate proactively, and fit naturally into a trust‑based virtual team.

What You Need to Have

• Proficient Full‑Stack Developer : You have solid professional experience with PHP and MySQL / PostgreSQL and are confident in contributing to a backend from day one. (Familiarity with Laravel is a strong plus!)
• Strong Frontend Foundation : You are proficient in modern JavaScript (ES6+), HTML, CSS, and Tailwind CSS. Experience with (or a strong desire to master) tools like Livewire and HTMX is a significant advantage.
• Professional Experience : You have 1‑3 years of experience working as a developer in a professional team environment.

Our Tech Stack

• Our Core (Day One) : PHP, MySQL, JavaScript, Tailwind CSS, HTMX, AWS
• Our Future (What You'll Help Build) : Laravel, PostgreSQL (as our main DB and vector store), pragmatic and interactive UIs (with tools like Livewire & HTMX), Python and natural language AI data querying via RAG LLMs (Vanna.ai)

We're looking for someone curious, collaborative, and eager to contribute and grow. We value potential and a passion for pragmatic solutions just as much as a CV that perfectly matches every keyword. If you're excited about this role but your experience doesn't tick every single box, we'd love you to apply anyway.

Who You'll Be Working With

You’ll join a small, ambitious, fully remote and growing team that works thoughtfully and keeps formalities light. We have two friendly hubs – Berlin and Huddersfield, West Yorkshire. Day to day you'll work with the Lead Developer (your manager), Founders (Product & Partnerships), UI / UX Designer and Data Analytics.

Our teams operate in six‑week cycles, fostering alignment, collaboration, and focus. This approach also allows for dedicated time for research and development, innovation scouting, and individual projects.

Why You'll Love Working With Us

• Direct Impact : You won't be a small cog in a big machine. You'll be a core member of the team, and your work will be visible and essential.
• A Clear Growth Path : This role is designed to grow. We want you to become our frontend expert and R&D leader, and we'll mentor you to get there.
• Time for Innovation : We value R&D. You'll have dedicated time to explore new tech, build prototypes, and help shape our roadmap.
• Work‑Life Balance : We genuinely prioritise work‑life balance. While we’re all driven by ambition for the company, we understand the value of personal time. You'll find a calm, respectful, and kind work environment here at Finfo – no corporate BS.

Benefits

• 30 days' holiday plus UK bank holidays.
• Company pension scheme
• Cycle to Work
• EV salary sacrifice schemes
• Funded co‑working space near your home
• Quality equipment and a supportive, fully remote setup

The Logistics

• Salary : £37,000 - £45,000 per annum (depending on experience)
